T0 ALL WHOM IT MAY GONCERN: Y

Beiteknown that 1, DEXTER AVERY, of Westfield, in the county ofHarnpden, and State of Massachusetts, have invented a new and improvedCarrier for Breitling-Machines; endl do'hereby declare that thefollowing is a full, clear, and exaet'descriptiou thereof', wine-huiltenable others'shilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which-'- Figure 1 represents a side view, partly insection, oi my improved carrier.

Figure 2 is a horizontal sectionaly view ci' the same, taken on theplane of the line x 1.

Similar letters of reference indicate corresponding parts. t

This invention relates to a/ne'w carrier for braiding-machines,theobject of which is to produce the required tension ofthe threads, toprotect` the spring (which-keeps the spring tense)frou1 wear, and tbobtain acomplete and eicctive carrier in the simplest and leastexpensive manner.

The invention consists in the manner ot guiding and protecting thespring, which works in a tubular holder, and around the hook-rod, towhich the thread is attached; also in a new manner of guiding thesliding catch, by which the intermittent motion ofthe bobbin isproduced, and in the general combination of all the parts, as will bchereinafter more fully described. j

A, in the drawing, represents the spindle, around whichthe bobbin Bturns, said bobbin resting .upon a dange, a, that is formed on thespindle. The spindle A is tub'ular, as shown, and has two shoulders, 6c, formed within its bore, so asfto have three variations of bore, asshown in tig. 1. The uppermost end ofthe bore is the narrowest, and thelowermost thc widest, as shown.

The spindle or carrier A has a suitable elliptic or other external shoe,d, which is between two danges, aa', and which moves in suitable guidesthat are on the frame of the machine.

From the ange a projects, upwards, a rod, e, which is parallel with thetube A, as shown.

Within the tubcIA is arranged a rod, C, which has ahool:` at its upperend, and a head,f, at its lower end. A spiral spring, D, is arrangedwithin the tube A, around the rod C, and between the upper shoulder band the head fot` the rod, as is clearly shown in fig. 1. i

The outside of the spring D only touches-,the tube A in that portion'ofthe same which is between the shoulders b and e.

Thelower part ofthe tube is too wide for the-spring toreach it, and justlarge enough for the head f to `play in. The spring is thus fullyprot'eetcd, and cannot wear against the tube, being completely guided bythe rodO. From the head f projects a lug, g, which iits through a slotin the lower part of the tube, and which i serves as a handle to morethe rod C up, to'havc itshook threaded. 'lhe bobbin B, upon which thethread is wound, has la: ratchet-formed at its upper end, as shown, andas usual.

Upon the rod a slides a slotted tube, E, from which an arm, z, projects,which arm rests upon the ratchetend of the bobbin. AA pin, t',projecting from therod e, itsthrough the slotl in the tube E, andprevents the same from turning, so that should the thread jbreak, thearm h may not fly round and strike the thread on another carrier,thereby also breakingv the same.

The end of the thread is, `fiornthe bobbin, brought through an eye, j,in the rod e,'thence laid over the forked end of the rod c, broughtthrough a loop in the end of the arm z, and then through the hook on theupper end of the rod C. i

The thread is then drawn once more through the eye in the arm 7i, andfinally through the upper end of the tube A, asis clearly indicated byred lines in.g.`1.

The spring D vkeeps the thread always tense, butstill allows the rod Cto be drawn up by the same. When the thread is pulled by the action ofthe machine, the bobbin cannot turn, as it is held by the arm i. The armC will, therefore, be drawn up until its hooked end strikes the end ot'the arm 7i, when the latter will be raised out ofthe ratchet so as toliberato the bobbin. Thereqircd quantity of thread is then takenfrom'thebobbin, the motion of which is again stopped by the arm hfalling into the next tooth of the ratchet.

The upper portion of the tube A, between the upper end of the bobbin andthe extreme upper end of the tube, is laid open, so as to facilitate thethreading ofthe hook, andvto enable the end of the arm 7L to be abovethe hook C.

Having thus described iny invention, what I claim as new, and'desire to-secure by LetterslPatent, is

The hollow spindle A, spring D, and hook-rod C, in combination with therod e, sleeve E, and arm h, all

made and operating substantially as and for the purpose flieieinshownand described. lDEXTER AVERY.
